This document contains reports of school district results on the Arizona Measure of Academic Progress by school and grade level for the 1999-2000 school year. Lengthy tables present results for reading and mathematics showing the change in achievement between grades each year from grades 2 to 3 to grades 7 to 8. The Arizona Measure of Academic Progress is based on percentile ranks on the Stanford Achievement Test, Ninth Edition (Stanford 9). For each school, data are provided to show the percent of expected gain and the 1999 Stanford 9 percentile rank. In many instances, data are not available for particular grade levels because too few students could be matched to prior year results. Two long tables show results for reading and mathematics for all the state's schools. (SLD)
